SPECIFICATION forming part of Letters Patent No. 271,643, dated February' 6, lSSS.

Application led October 24, 18H-2. (No model.)

To all whom it may concern Beit known that I` SHERMAN E. LIMPUs, of Olathe, Johnson county, Kansas, have invented cert-ain Improvements in Windmills, ot'.

which the following is a specification.

My invention is a windmill constructed, as fully described hereinafter, so as to reduce friction, utilize to as great an extent as possible the full force of the wind, secure a ready application of the power for different purposes and in different ways, and facilitate the adjustment ofthe parts.

In the drawings, Figure I is a sectional elevation of a windmill with my improvements, and Fig. 2 is a plan view.

The frame A, of any suitable character, supports a platform, B, provided With frictionrollers a, on which rests and revolves a circular table, C, having peripheral friction-rollers b, which bear upon the inner side of a fixed rin g-bearin g, d, supported by the platform. rIhe table U carries the bearings of the windwheel shaft D, which has the wind-wheel E at one end and a crank, e, directly central with the table, a pitman, f, connecting said crank with a link or slide, F, sliding in a guide-yoke, G, that is secured to the table. As the shaft D revolves'the slide F moves up and down in its guide and carries with it the pump-rod g, which is secured to the lower end of the slide. By this means a very direct connection is made between the crank-shaft and pump-rod, and a transfer of motion attended with but little friction orjerking, while the parts are so protect-l ed as not to be liable to injury from storms or disabled by snow or ice. the thrust from the action ot' the wind upon the wind-wheel; but the peripheral rollers b prevent any such friction between the latter and bearing as will interfere with the free turning of the structure to keep the wheel face to the Wind.v I

The proper presentation of the wheel tothe Wind is secured by the tail-blade H, secured xedly or adjustably to the table. As shown,

1 the tail has an arm, s, pivoted at :v to the table and held in either of the positions shown in full and dotted lines, Fig. 2, by a .latch-le ver, I, pivoted at y to the yoke G. The lever I has notches which receive and hold the arm The table C receives v l s when the tail is in either position. When the tail is in the working position shown in Fig. 2 it can be moved by drawing on a cord, m, which is attached to one side of the tail and passes over a pulley on the end of the lever I. The rst draft upon the cord tilts the lever and raises it from the arm s. The tail is then drawn by a continued pull ou the cord to the position shown in dotted lines, thus throwing the apparatus outof action. To bring the tail again to working position, a cord, a, is pulled down, this cord passing from its attachment at one side ot' the tail beneath the end of the lever I and up to an eye in an arm, J, secured to the yoke G, and downward. The first pull raises the lever and releases the arm s, and the continued draft draws round the tail to the position shown in full lines. I do notlimit myself to this mode of adjustment, as other means may be adopted for effecting the saine object.

It is sometimes necessary to transmit the rotary motion ofthe wind-wheel for different purposes;. or both a reciprocating and a rotary motion are required. To secure this I mount a miter-pinion, K, upon the shaft D, and put a similar pinion, L, upon a sleeve, M, revolving on the pump-rod and resting in a slot on the frame. Bevel-gear N transmits motion from-the sleeve M to a shaft carrying a handpulley, O. As it is sometimes necessary to throw the sleeve M out of gear with the shaft D, I make the pinion L movable by fitting it to slide on a square end of the shaft D. Different means of adjusting this pinion L may be adopted. Thus the forked end of arod,I, may fit an annular groove in the pinion L,

carrying the pinion with it. I claim- Y 1. The combination, with the supportingrolls a, supported thereby, a table resting on saidA rolls inside a bearing-ring, d, with peripheral rolls b, and carrying the crank-shaft of a pitman to said shaft, substantially as setforth.
